The lowest tier of the stage was hung
with the Triumphs of Petrarch, also painted by
Mantegna, and large golden candelabra hung from
the centre of the roof, each holding three double
rows of torches and a shield with the arms of His
Caesarean Majesty, the black eagle with the royal and
imperial diadem.

Another part of the decoration are six pictures from Mantegna to the Triumph of Caesar.

One might think, that the story appears in Petrarca's text. True, but with some distance ...

Behold the jealous Juno, and the blond
Apollo, who once scorned the youthful bow
That dealt him such a wound in Thessaly.
What shall I say? To put it briefly, then,
All Varro' s gods are here as prisoners,
And, burdened with innumerable bonds,
Before the chariot goes Jupiter.
